Another Interesting fun fact, Philo Farnsworth (the man behind the Capehart and Farnsworth Radio and TV Company) actually was a pioneer in early TV manufacturing and had many patents in TV development which RCA ripped off from him, and when Philo tried to sue RCA for patent infringment they took him for a ride and drove him into bankruptcy.
So the majority of those Patent Nos. refrenced to on the back of these TVs that are claimed by RCA are actually Farnsworth Patents NOT RCA Patents.
